MEANS FOR SEPARATING AIRTROMLIQUIDHN CARBONATING OR OTHER APPARATUS.

SPECIFICATION forming part of Letters Patent NO. 727,570, dated May 12, 1903. Application filed February 15, 1901. Serial No. 47,462 (No model.)

To all whmn it may concern:

Be it known that 1, CHARLES L. BAS'IIAN, a citizen of the United States, residing at Ohica go, in the county of Cook and State of Illinois, have invented new and useful Improvements in Means for Separating Air from Liquid in Oarbonating or other Apparatus, of which the following is a specification.

This invention relates to novel means for separating air from liquid while being induced by a pump or other means to flow from a source of supply to a receiver, and it is especially adapted for carbonating apparatus,

although it may be used in other connections with equally good results.

The object of the invention is to provide an air-chamber of novel construction arranged between the pump and mixer of a carbonating apparatus or inthe discharge-t pipe of a pump used in any connection for separating air carried along with the liquid from the pump and collecting the air in the air-chamber to prevent it from passing into the mixer or other receiver with the liquid and so that it will form an air-cushion.

In the accompanying drawings, Figure 1 is a perspective view of an improved type of oarbonating apparatus embodying my invention. Fig. 2 is a sectional view of the collooting-tank.

In the drawings I have shown an apparatus constructed in accordance with my Letters Patent No. 609,867, dated August 30, 1898, to illustrate the manner in which the present invention may be used. It will not be necessary to enter into a detailed descriptionof the parts of this apparatus, except to say that the pump A is operated from the shaft B, carrying a pulley O, to which power is communicated in any suitable way. B is an agitator-shaft carrying an agitator, which may be continuously or intermittently driven to thoroughly saturate the liquid with gas in the mixer E. The pump forces the liquid through a pipe F into the mixer,and in order to prevent air carried by the liquid from entering the mixer I provide in the pipe F a separating and collecting tank G, into which the liquid may be discharged at any point, but is drawn off from beneath the level of the liquid in said separating and collecting tank, so that the air carried by the liquid from the pump will collect in this tank upon the surface of the liquid therein and not be drawn off therefrom through the outlet-pipe.

The separating and collecting tank may be constructed in several different ways to attain the desired result. In Fig. 2 I have shown one section of the pipe F connected to the pump and discharging into thebottom of-the tank G anda section leading out of the top of the tank and emptying into the top of the mixer, a continuing section H being connected at its top with the outlet in the top of the collecting-tank and extending down nearly to the bottomthereof and beneath the level of the liquid therein. In view of the fact that it is more convenient to arrange these pipes in the center of the tank I plug the lower end of the section H and provide the same with side openings g; but this is a detail which may be changed without departing from the invention.

To secure the pipe H in the tank and the tank to the pipe F, I provide a coupling L, which is fitted in an opening in the top of the tank and provided with a peripheral flange M, arranged underneath the top and secured thereto by soldering or in some other suitable manner. The upper part N of the coupling is interiorly threaded to receive the exteriorly-threaded endv of the pipe F, and the lower part 0 of the coupling within the tank is interiorly threaded to receive the exteriorlythreaded upper end of the pipe-section H. This construction provides for supporting the tank in a firm and rigid manner in connection with the carbonating apparatus by means of thepipe F.

When a carbonating or other apparatus is provided with my present invention, the liquid is brought from a source of supply and forced by a pump or in some other Way through the pipe F and into the tank G. The air carried by the liquid becomes separated from the liquid in this tank and collects at the top thereof, so that it will not be drawn off through the outlet at the bottom of the tank and beneath the level of the liquid therein. I provide a water-gage I on the tank G, so that the level of the liquid in said tank may be observed at all times, and when an excess of air has been collected it may be allowed to escape through the cock K.

In this tank will form a cushion to relieve the apparatus of shock due to the pulsations of the pump and starting and stopping the same, and as the cock K is located below the top of the tank some air will always be left in the tank to form this cushion.

Having thus fully described myinvention,

What I claim, and desire to secure by Letters Patent, is.-

In a carbonating apparatus, the combination with a mixer and a pump for supplying liquid thereto, of a tank arranged between the mixer and the pump and provided with a blow-0H cock, a liquid-pipe leading from the pump and connected to the bottom of said tank, a pipe-coupling arranged in an opening in the top' of the tank and provided with a. peripheral flan ge on which the top of the tank rests, a pipe-section arranged within the tank and secured to said coupling, and a pipe secured to the upper end of said coupling and leading. to the mixer, substantially as described. 7
